Phil Sayer, who originally worked as a BBC presenter, died on Thursday of cancer.
Following a career at the BBC, in which he worked on BBC GMR and regional TV news, he and his wife Elinor Hamilton set up a company as voice-over artists.
The company said on Facebook: "Phil Sayer - voice of reason, radio, and railways. A dearly loved husband, father, grandfather, brother, uncle and friend.
"We are sorry to announce that this service terminates here."
Londoners have heard his voice every day without knowing his name, but tributes have already starting pouring in with people praising his "fantastic voice".
Sad Phil Sayer's died - the voice of many of Britain's railway stations for a long time. What a voice.— Tom Hourigan (@TomHourigan) April 15, 2016
I was only listening to Phil Sayer on the train yesterday! RIP and may your voice keep us safe from the gap! #mindthegap— David P Perlmutter (@davepperlmutter) April 15, 2016
